As the name implies, the stable currency is a cryptocurrency with stable value due to the sharp fluctuations in the currency price.   As Ethereum gradually becomes a prerequisite for synthetic assets, in the future, how many stable coins are likely to run on the Ethereum blockchain is worthy of serious observation. Dovey Wan, founding partner of Primitive Ventures, said that the company is preparing to change the USDT recharge address to ERC20 in Ethereum. On July 3, the announcement of the currency security announced that the default recharge cash withdrawal address of the USDT would be changed from the OMNI network to the ERC20 network. On July 5, 2019, the Bitfinex CTO said on Twitter that the 100 million USDTs established on July 4 were to move Tether from OMNI to Ethereum.
